Citrix adds MCP Gateway to NetScaler for AI traffic
Fri, 10th Jul 2026 (Today)
Citrix has added MCP Gateway functions to its NetScaler platform, extending NetScaler AI Gateway to govern both agentic AI and large language model traffic from one system.
The update is intended to give enterprises a single entry point for AI-related traffic as they deploy agents that connect to internal applications, tools and data through Model Context Protocol servers.
NetScaler AI Gateway was introduced earlier this year for large language model traffic. The latest release adds controls for traffic between AI agents and backend MCP servers, an area Citrix argues is becoming harder to manage as organisations move beyond pilot projects.
Under the new setup, enterprises can route requests from MCP clients to approved backend servers through a governed gateway, rather than manage separate endpoints and authentication methods across different systems. The approach includes centralised authentication, tool-based rate limiting, and allow or block lists for servers.
The platform also adds session persistence and protocol-aware monitoring for agent workflows involving multiple steps and longer-running interactions. On the large language model side, NetScaler AI Gateway now supports policy-based model routing and usage tracking by team, user or application.
Citrix is positioning the software as a way for security, infrastructure and AI platform teams to monitor both sides of enterprise AI adoption through one dashboard. That includes traffic going to language models as well as requests sent by agents into enterprise systems through MCP.
The move comes as businesses seek tighter control over AI experiments connected to sensitive systems. Citrix cited Gartner research saying 60% of generative AI proof-of-concepts were abandoned after completion in 2024, and that the figure would fall to 35% in 2029.
Governance focus
Steve Shah, General Manager of NetScaler at Citrix, said the growth of AI agents would make governance at the protocol layer more important for security and compliance teams.
"As agents become pervasive elements of the modern enterprise, querying systems of record through MCPs will become the new API call," Shah said.
"Protecting systems of record with clear policies for who can access which services, and ensuring that such requests are handled safely, will be key for modern security and regulatory compliance. It is not a matter of if, but when, cyber-insurance requirements will mandate the use of MCP gateways to protect against dangerous agents. NetScaler MCP Gateway helps enterprises position themselves for a new reality in which MCP gateways will be a requirement for AI risk mitigation."
The gateway is aimed particularly at regulated sectors including financial services, healthcare and the public sector, where audit trails and controlled access are central requirements when software agents interact with core business systems.
MCP, an emerging standard for linking AI agents to enterprise tools and applications, creates a new management layer for IT teams. As more servers, credentials and usage policies are introduced, companies can face the same kinds of access control and visibility issues seen in earlier API roll-outs, but with less predictable traffic patterns.
Traffic handling
Another part of the announcement focuses on traffic processing. NetScaler uses a single-pass architecture that handles authentication, routing, security inspection, observability and rate limiting in one path through the system, rather than chaining together multiple proxy tools.
Citrix argues this matters because AI traffic can be both packet-heavy and data-heavy, and extra inspection hops can add delay where response times are sensitive. The same architecture is also intended to support longer agent workflows that depend on stable sessions and consistent server assignment.
Citrix also disclosed a private technology preview tied to Claude Code. In that setup, NetScaler AI Gateway sits in front of Anthropic model access through a service provider, giving administrators one control point for developer access across large internal user groups.
The arrangement is designed to avoid duplicate identity enforcement while giving companies flexibility to route demand across providers. The feature is aimed at organisations with thousands of developers using AI coding tools.
Commercial terms
For customers using Citrix Platform Licence or Universal Hybrid Multi-Cloud, the NetScaler updates are included at no extra charge. Those licences include unlimited NetScaler instances and bandwidth, according to Citrix.
Citrix also said it already uses NetScaler AI Gateway as part of the control layer for Citrix Aidrien, its in-product AI assistant. The system governs every prompt, model interaction and token used by that assistant inside the company's own operations.
